What should the Lux readings be at seedlings , veg, and flowering?
Light intensity is measured in PPFD for plants, as plants see a wider spectrum of light than can be indicated by lux. There’s a free phone app out there named Photone that will measure PPFD for you. The guidelines are:
Seedling: 300 PPFD
Veg: 600 PPFD
Flowering: 800 PPFD

I have the Photone app, Was wanting what the Lux readings should be at all stages of growth. Just to double check.
Lux isn’t relevant for horticulture. Plants use a wider spectrum of light than is measured by lux.

Figures used the lux to ppfd conversion calculator on HLG web site.
